with rounded, knob-like crest of metallic scales; eyes moderate, tibiae unarmed; 
primaries with termen well rounded, veins Cu, and Cu. approached from well 
before angle of cell, vein M2 from above angle, R; and Ry stalked from apex of 
areole, R: from areole, Ri free; secondaries with Ms; and Cu: connate from 
lower angle of cell, Mz nearly fully developed from just below middle of dis- 
cocellulars, S. C. joined to cell only at base of wing. 
The genus is apparently closely related to Cerynea Wlk. (Hamp- 
son, Cat. Lep. Het. X, 209). The rounded tuft of metallic scales on 
metathorax, somewhat similar to, but smoother than in Ovycnemis is 
one of the chief points of distinction. The specimens before us have 
had the thorax rather crushed owing to being papered but as far as 
we can judge there are no prothoracic crests. 
H. cLeortrormis sp. nov. (PI. IV, Figs. 10, 11). 
Distinctly geometriform in appearance, resembling a small specimen of 
the genus Cleora; dull white, heavily clouded and powdered with smoky-brown; 
a triangular brown costal spot near base of wing, beyond this a larger, more 
diffuse patch, marking the inception of the t. a. line; from this an indistinct 
wavy brown shade crosses the wing, preceded in the cell by a slight brown 
dot; reniform an oval brown spot; beyond cell and touching t. p. line a minute 
dot, at times obsolete; t. p. line most distinct feature of the maculation, white, 
dentate, bordered by brown scaling, outcurved below costa, incurved slightly 
opposite cell, then irregular and subparallel to outer margin; subterminal space 
shaded with brown, most noticeable as a costal patch and again above inner 
margin; subterminal line defined slightly by a brown terminal patch between 
veins 3 and 5, otherwise obsolete; prominent row of dark brown terminal 
lunules; fringes white, checkered with brown. Secondaries very similar to pri- 
maries in general appearance, marbled and suffused with brown, with faint 
continuation of t. p. line of primaries and rather prominent brown patch above 
anal angle; small brown dot in cell; inner margin rather paler and crossed by - 
several brown lines; fringes and terminal line as on primaries. Beneath, pri- 
maries suffused with smoky, slightly ochreous along costa with indistinct brown 
markings; secondaries paler, with traces of ante-median and post-median lines 
and discal dot; fringes of both wings as above. Expanse 22-25 mm.

We have been unable to find anything at all corresponding to this 
species ; it is possible it has been described as a geometer, but if so we 
have not succeeded in identifying it.
